The Twin Huey entered the Air Force inventory in 1970 to provide search and rescue capabilities but soon expanded to include missile sites support, VIP and air adviser operations. They are assigned worldwide and eventually replaced both the HH-1H and UH-1F single engine Iroquois

On August 1st 2014, the 3 remaining squadrons flying the UH-1N in support of the USAF intercontinental ballistic missile (ICBM) force ( 37th HS, 40th HS and 54th HS ) were merge into a single unified command, based at FE Warren AFB, Wyoming named 20th Air Force Helicopter Operations Group (20th AF HOG).
USAF UH-1 replacement
On 2011, with 62 of them still in service, USAF launches a competitive bidding process for a 93 new helicopters request known as the Common vertical lift support platform ( CVLSP ) programme. The five most likely helicopters competing are at least 50% larger than the UH-1N, ranging from the 6,800kg AgustaWestland AW139M to the 22,700kg Boeing HH-47. Falling in between are the Bell UH-1Y, Sikorsky UH-60M and the Eurocopter EC725. But the CVLSP was killed in the Pentagon fiscal 2013 budget proposal and USAF meant to received up to 30 recently retired ex USMC UH-1Ns and a program to modernize all surviving aircraft was expected to begin by 2015.
In 2014, the Air Force Requirements Oversight Council (AFROC) recommended replacing the UH-1N with US Army UH-60A Black Hawk by upgrade them to the L variant at an estimated cost of $10 million per aircraft. Known as UH-60A2L program, 62 UH-1Ns have to be replace by 72 Black Hawks for $980 million with expected initial deliveries by September 2017 and continue into the early 2020s.
As of 2017, new candidates includes the HH-60U ( allegedly 85% similar to the HH-60W ) and the MH-139
On September 24, 2018 USAF selected the Boeing/Leonardo Philadelphia MH-139A Grey Wolf
One unidentified UH-1N was lost in training on 1973 at Brass Key II near Fort Bragg
The 72nd HD that was stationed at Langley FL Virginia. The unit was responsible for transportation in support of the Dare County range.range support was the primary mission of the squad on and we typically flew missions to Seymour Johnson AFB then over to the range, we would do off the person ell, fly over to Dare County, fuel, have lunch, then reverse the tip. The secondary mission was via support for ACC HQ. This generally entailed flying O7s and above to the Pentagon and back. We had 6 aircraft assigned,I believe 4 PA and 2 BA UH-1Ns. The ba aircraft came from the deactivated Ramstein unit in 93.The squadron was under the 1st Fighter Wing.the unit was deactivated in 95 o 96.
